POCKET VAPOR CIGAR LIGHTER Filed March 23, 1927 MZ-m/mm/M Patented. June 17, 1930 UNITED STATES PATENT OFFICE EDWARD I. CLARK, OF NORTH ATTLEBORO, AND JULIAN H. MURDOCK, OF HOLBROOK, MASSACHUSETTS, ASSIGNORS, BY MESNE ASSIGNMENTS, TO CLARK LIGHTER 00., INCL, OF NORTH ATTLEBORO, MASSACHUSETTS, A CORPORATION OF MARYLAND rooxm vnro'n. CIGAR LIGHTER Application filed March 23, 1927. Serial No. 177,744. I

Our invention is a pocket vapor cigar lighter, in which the lighter is made up of a metallic head carrying the working parts and a molded fuel container of non-metallic substance, such. as hard or vulcanized natural rubber, synthetic. rubber or synthetic resin, or the like, the two elements being hermetically locked together by a connectlon applied first in liquid form, and formed or molded between the metallic and non-metallic elements and converted into a solid interlocking element integral with the molded box.

In the drawings:

Figure 1 is a side elevation of a cigar lighter;

Figure 2 is a central longitudinal section, parts being in elevation, of our cigar lighter, upon an enlarged scale;

Figure 3iis a detail, partly in sectlon, of the upper end of the hghter, on the same scale as Figure 1;

Figure 4 is a bottom plan view of the lighter on the scale of Figure 2.

In the drawings 1 is the fuel container and 2 is the metal top plate, u on which are mounted the working parts o a lighter, such, for example, as is shown in Letters Patent of the United States 1,594,047, dated July 27 1926'. As the lighter" mechanism is no part of the present invention it will be unnecessary to further describe it.

The fuel container in our-invention is to be made of hard vulcanized rubber or synthetic rubber orsynthetic resin. Such materials are originally in plastic condition and while in this condition may be molded in an desired shape.

fuel is usually alcohol, gasoline'or other highl volatile-fluid it is practically essen tial t at any 'oints which exist should be perfectly scale and this requirement, where the fuel container is of metal, requires very close fit and is relatively an expensive method of manufacture with a certain portion of imperfect products, rendering the articles unsalable and unusable. p

In our molded container there are no joints or openings which are not absolutely For a container for, the hquid fuel of a cigar lighter, which bottom wall of the container, which is made thick enough to receive the tangs 12 within its thickness. The tangs 12 are preferably angular in cross section so that the shoes cannot Work loose and turn upon the tangs as a pivot (see Fig. 4). In the centre of the bottom wall we provide a screw threaded filling aperture into which is screwed a lug 13 having a lmurled disk 14 integral tlibrewith, by which the plug 13 may be tightly screwed home.

The upper open end of the container 1 is closed and hermetically sealed as follows: a metal top plate 2 is provided, u on which arev mounted the mechanical wor 'ng parts of the lighter which may beas desired. I

have shown in the drawings the working elements of United States Patent 1,594,047.

I In connection with the top'plate 2 we employ a metal cup or oonnectorelement 22 which is rovided-with an aperture, registering wit an aperture in the top plate 2, for the passage of the wick of the lighter which is within the burner In Figure 3 we have shown the top plate 2 and cup 22-separated. In use the cup and top plate are brazed together to form' a unitary structure, as shown in Figure 2. Thedepending sides or flanges 23 0 cup '22 are grooved-,as at 24, and upon the outer surface of these depending sides is applied a rather thick film of viscous synthetic resin. The cup is then passed into the open end of the container 1, the liquid resin being wiped back from the free edge of the cup, filling the groove 24,

any surplus being carried beneath" the pro jecting edges of the top plate 1 and exuded over the upper edges of the container 1.

in process, the .liqui The structure now bein subjected to a bakresin between the si es 23 and container walls hardens into a unit with the walls of the container 1, a portion of the resin forming an integral bead 15 filling the groove 24 around the outer surface of sides 23, so that the cup 22 and connected top late 2 are locked to the container v1. The 1m of resin between the side 23 of cup 22 and the inner surface of the container 1, from its fluidity is spread perfectly and with a perfect fit between the sides of the cup and the walls of the container, and is hardenedby the baking process, along with the bead 15. The result is a perfect joint, perfectly locked and perfectly fitted with no special care or expensive fitting process.

We have in the drawings indicated the bead 15, which beginning as a liquid is by the curing process converted into a solid integral with the wall of container 1, by a solid black to call attention to that portion of the wall of container 1 which is added as a liquid after the molding of the container and changed by a curing process into a solid condition integral with the container.

We claim: I

1. In a cigar lighter, an open ended molded fuel container; a bottom'plate structure and a top plate structure, said top plate structure comprising a top plate having a wick hole therein and an inverted rectangular cup also having a wick hole therein brazed to the under side of said plate in such fashion that the wick holes in the top plate and cup register, said cup having gro'oved faces acting as depending flanges adapted to fit within the open end of said molded container; a bead adherent to the container wall adapted to fill the groove, lock the parts together and hermetically seal the joint between the container and faces.

2. In combination, with a cigar lighter structure having its top plate structure sealed to a molded volatile container body, a top plate and a grooved inverted rectangular cup adapted to be brazed to the underside of said top plate to form the top plate structure, a seal adapted to seal said cup to said body comprising a synthetic resin bead formed and baked in the groove in said cup and adherent to the molded body, and a thin layer of synthetic resin joining said cup over each of its faces to the inner Walls of said molded body.

3. In combination, with a cigar lighter structure having its top plate structure sealed to a molded volatile container body, a top plate having a wick-hole therethrough, a grooved inverted rectangular cup also having a wick-hole therein adapted to registry with the wick-hole in the top plate and adapted to be brazed to the underside thereof to form the top plate structure, a seal adapted to seal said cup to said body conirism a. synthetic resin bead formed and aked 1n the roove in said cup and adherent to the molded body, and a thin layer of synthetic resin joining said cup over each ofits faces to the lnner walls of said molded body.

4. In combination, with a cigar lighter structure having its top plate structure sealed to a molded volatile container body, a top plate and a grooved inverted rectangular cup adapted to be brazed to the underside of said top plate to form the top plate structure, a seal adapted to seal said cup to said body comprising a bead of 'a cementitious material formed and baked in the roove in said cup and'adherent to the mol ed body, and a thin layer of cementitious material joining said cup over each of its faces to the inner walls of said molded body.

5. In combination, with a cigar lighter structure having its top plate structure sealed to a molded volatile container bod a top plate having a wick-hole therethroug a grooved invertedrectangular cup also having a wick-hole therein adapted to registry with the wick-hole in the top plate and adapted to be brazed to the underside thereof to form the top plate structure, a seal adapted to seal said cup to said-body comprisin a. bead of cementitious material for'me and baked in the groove in said cup and adherent to the molded body, and a thin layer of cementitious material joining said cup over each of its faces to the inner walls of said molded body.
